Exempel

I följande exempel finns ett arbetsflöde med .WorkflowApplication En WorkflowApplication instans skapas med hjälp av en arbetsflödesdefinition som består av en enda DiceRoll aktivitet. Aktiviteten DiceRoll har två utdataargument som representerar resultatet av tärningskaståtgärden. När arbetsflödet är klart hämtas utdata i Completed hanteraren och följande utdata visas i konsolen.

Workflow aae3fb48-7229-4737-b969-d63e131b96b3 Completed.
The two dice are 1 and 5.

public sealed class DiceRoll : CodeActivity
{
    public OutArgument<int> D1 { get; set; }
    public OutArgument<int> D2 { get; set; }

    static Random r = new Random();

    protected override void Execute(CodeActivityContext context)
    {
        D1.Set(context, r.Next(1, 7));
        D2.Set(context, r.Next(1, 7));
    }
}

 // Create a WorkflowApplication instance.
 WorkflowApplication wfApp = new WorkflowApplication(new DiceRoll());

 // Subscribe to any desired workflow lifecycle events.
 wfApp.Completed = delegate(WorkflowApplicationCompletedEventArgs e)

         // keyed by argument name.

I följande exempel finns ett arbetsflöde med .WorkflowApplication En WorkflowApplication instans konstrueras med hjälp av en arbetsflödesdefinition som består av en enda Divide aktivitet som tar två indataargument och en ordlista med indataargument som innehåller de två värden som ska skickas, med argumentnamnet som nyckel. Önskade livscykelhändelser för arbetsflödet hanteras och arbetsflödet anropas med ett anrop till Run. När arbetsflödet har slutförts visas följande utdata i konsolen.
